Abstract

This paper contributes to investigations in the context of uncertainties of modern CFD methods by considering the numerical simulation and analyses of wind tunnel experiments including all geometrical and aerodynamic conditions – a so-called numerical wind tunnel. The computational method described is based on investigations within the DLR project ForMEx outlined for the wind tunnels DNW-NWB and ETW. Certainly aiming at the improvement of today’s wind tunnel testing techniques, e.g. CFD based wind tunnel corrections, and improved understanding of the flow physics the project results also represent an excellent data base to study uncertainty effects of the used CFD approaches.
